Serial No. 379,903 zrolaims. (01. 268-117) Casement windows present a very definite problem as tothe manner of actuating and locking them. This is particularly true if such winthe screen directly to thecasement frame,'and

one that is entirely mounted. upon the metal casement frame itself so that the structure is selfcontained, or complete with the setting; of

the frame in the window opening. Features and details of the invention will appear from the specification and claims. n Y

A preferredvembodiment of the invention is illustrated in the accompanying drawing as'follows:-- I r Fig. 1 shows a vertical sectionof the window, 20 the sash being partly open. 1"

1 marks the casement frame. This is ofthe usual angle section having an inner face memher 2 which forms the stop for the window. 1 The angle section has an outwardly extendingmember 23. 5 and is hinged by means of a pin 6-on a hinge projection 7 extending from the frame. Thus in the usual manner. 1

A rack bar 8 is slidingly mounted on the member 3 at thebottozn of the window frame. It. is provided with a rack 9 along an up-turned inner edge. The outer edgeoftherack bar 8 is beveled at 10 and a guide plate 11 having a similar bevel is secured by screws l2'on the member 3. Thus the rack bar is slidingly mounted in. the bottom of the windowframe. i A gear segment 13-extends throughan opening- 14 in the member 2 and meshes with the rack 9. The. .gear segment is ,carriedby a mounting 15 having the upper and lower plates 16 and '17 respectively. These plates are secured together 3 of the window frame by screws 31.

A window sash '4 has a hingeprojection v the hinge is off-set from the plane of the'frame and have the extending flanges 18 through which screws 19 extend for securing the mounting to the front of thelface member 2. The gear segment is pivoted on a bolt 20 which'extends through-the plates 16 and '17. The holtis provided with a nut 21 at the bottom. Ajscrew 22 extends through a slot 23 inthe plate 16 and is secured in a screw-threaded opening 24 in the gear segment. The screw is provided with a handle 25 and with. a'clamping shoulder 22a. As the segment is thrown to any position the screw 22 is operated clamping the plate 16 betweenfthe gear segment and the shoulders 22a,

thus locking the handle in any adjusted position. v

and is provided withthe ordinary handle "13b.;

The sliding motion of the rack bars is conveyed to the window sash throughtheffollowihglever mechanism: A lever 26 is pivotally connected at 27 with'the window sash and isslid ingly'mounted by means of a pin 28 on a plate 29, the plate being provided with. a slot 30'through whichthe pin 28 extends. The plate 29 is secured to the member A thrust link 32 is pivotally connected by a pin 33 with the lever 26 and by a pin 34 with the rack bar 8.

The operation of the mechanism is as follows;

With the window in closed position, the lever 26 rack bar proceeds,v the link 32 gradually assumes and the thrust link 32 are arranged below the e at "position more nearly at right angles to the V fra'rnegand thusthe thrust of the bar lever-25..

on the sash is outwardly. By, this time the ofiset'hinge piece 5 is'more nearly crosswise of the 7 nearly at a right angle so that very little locking T "force of the screw 22 will lockthe" window in this position. I.

It will be. noted that thisdevice involves a lever mechanism inside 'the window frame,'- and a second 1 lever mechanism outside the window frame. these lever mechanisms having pivotal connectionsythe axes of which are parallel, and that the movement of the inside lever'mechanism frame, as :40.

' of the bolt 20.

is communicated to the outside lever mechanism without any moving shutter, or other-device for maintaining a closure through the easement frame. It will also be noted that the device occupies a very slight space vertically on the member 2 of the frame. tion of the inner face of the window frame is available for direct engagement by. a screen In this structure, the screen frame rests on the top plate 16 and is within the inside It will also be noted that by reason of this small space used vertically that the wall structure inwhich the casement frame is set may extend, if desired, up "the face of the member. 2 so as to make the proper finish.

In Figs. 5 and 6, an alternative construction for locking the gear segment is used.- The plates 16 A pawl 37 is slidingly comprising a lever'pivotally connected to the sash the lever between its connections;

and slidingly connected to the frame, said connection to the frame being remote from the hinge and locating the pivotal connection with the sash between said frame connection and the hinge with the sash in closed position and a linkconnected to and means actuating the link. r
